The -Effect from a Multimode Squeezed Graviton State
Nick E. Mavromatos, Sarben Sarkar
The -effect in entangled neutral-meson systems provides a sensitive probe of CPT violation induced by quantum-gravitational environments. In open quantum systems, interactions w…
How Much Can Gravitons Be Squeezed?
Panagiotis Dorlis, Nick E. Mavromatos, Sarben Sarkar +1
Quantum Gravity remains elusive, largely because its observable effects are suppressed by powers of the Planck scale. Direct detection of single gravitons is widely believed to be…
The axion coupling accelerates the Universe through PT-symmetric phases
Leqian Chen, Nick E. Mavromatos, Sarben Sarkar
The conjecture by two of the authors (N.E.M. and S.S.) that a \cPT-symmetric phase plays a role in understanding singular renormalisation group (RG) flows for a Chern-Simons (CS) g…
